swrrcn CONTROL.

Application filed May 5,.

[o 117/ I('/l(ll)l it may concern:

lie it known that we, ARNOLD (l. NuwsoM and Znn (own-1v. citizens of the- United States. residing at Iieatha, in the county of llfagollin and State of Kentucky, have invented new and useful Improvements in Switch Controls, of which the following is a specification.

'lhis invention relates to a. switch controlling device the general object of the invention being to provide time controlled means for opening an electric switch at any desired time.

Another object of the invention is to provide means whereby an ordinary alarm clock can be used to open the switch at the time desired.

This invention also consists in certain other features of construction and in the combination and arrangement of the seven a1 parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing our invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a view showing how the invention is carried out.

Figure 2 is a similar view but showing the switch in open position.

Figure 3 is a horizontal section through the clock housing.

Figure 4 is a detail view showing how the roller is supported on the end of the spring.

Figure 5 is a sectional detail view of the reel on the alarm key.

Figure 6 is a section on line 66 of Figure 5.

Figure 7 is a sectional detail View through the lower part of the clock housing and showing the means for holding the clock therein.

Figure 8 is a detail View showing how the leg of the clock is held to the housing.

In these views, A indicates the switch which is to be opened and 1 indicates a housing or casing which is supported on the bracket 2, fastened to a suitable support B, said housing containing an ordinary alarm clock C which is held to the bottom of the housing by the clips 3 which engage the legs and a portion of the flange 1924.

at the rear of the clock. A reel 4 is formed with the winding key '5 of the alarm mechanism and a cable 6 has one end connected with this reel and its other end to the switch lever of the switch A. Thiscable passes through holes in the housing and in the support B. A second cable 7 is connected with the reel 4 and to the alarm control 8, said cable passing over the guiding pulleys 9 and 10, the pulley 9 being suported from the housing and the pulley 10 )eing connected to a coil spring 11 which is connected with the bottom of the housing. The pulley 10 and its spring 11 tend to hold the cable 7 taut at all times. I prefer to fasten the cables to the reel by passing the ends of the cables through holes 12 formed in the reel with their extremities knotted to prevent them from being drawn through the holes and then the cables are given a turn around the reel, as shown in Figures 5 and 6.

From the foregoing it will be seen that when the alarm mechanism is wound up and the cables connected with the switch lever and with the alarm control 8, the parts wvill be in a position shown in Figure 1.

Then when the alarm mechanism begins to operate at the time for which it is set the reel will be rotated so that the cables will be wound thereon and thus shortened so as to first open the switch A and break the circuit in which the switch is located and then the cable 7 will move the control 8 downwardly to shut off the alarm mechanism. This invention is mainly designed for breaking the lamp circuits in store windows and the like where the lamps are lighted for permitting persons to observe the goods displayed in the windows at night and where it is desired to extinguish the lamps when the streets have become deserted. By our invention the alarm. mechanism can be set to operate at any hour desired or a fraction thereof and when this time occurs the lamps will be extinguished. Thus it is not necessary for the store owner to go back to the store to turn out the lights or to keep them on all night.

We provide hinged doors 13 for the easing so as to provide access to the parts therein.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

We desire it to be understood that we may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What we claim is:

Means for opening an electric switch, comprising a clock, a reel formed with the winding key of the alarm mechanism thereof, a cable connected with said reel and with the switch, a second cable connected with the reel and with the alarm control lever of the clock, a spring connected with the stationary part and a pulley on the 5 ring tures.
